HIS HD6990 Dual CrossfireX Review

Stone Giant is a benchmark tech demo that showcases and measures DirectX 11 performance using the BitSquid Engine. This is a tessellation heavy benchmark that, traditionally, runs very well on nVidia hardware. The jump in measured tessellation performance by the Radeon HD 6990 was so surprisingly high, that we re-ran the test several times to make sure the results were accurate.

CrossfireX performance with Stone Giant is all over the place, we recorded between 240 and 260 fps with this engine. Hard to get a grip on the scaling, but regardless its interesting enough to merit an inclusion – the new AMD optimised driver setting was used with the HD6990 which would account for some of the variances. We have included a video of a run of the Stone Giant benchmark above.

  1. lol, bet you wish they could run in a 3x 6x setup !

  2. 14,000 in 3dmark 11. I thought i was doing well, breaking 5k last week 🙁 I suck.

  3. Wow. just wow. AMD are owning everyone this week……..

  4. YAY! 48k in vantage. insane, this card just friggin rocks.

  5. I wouldnt be getting all too excited just yet, Nvidia have yet to unleash the GTX590 which I would think might kick the 6990’s arse.

  6. The nvidia architecture is slightly more powerful overall, but its all about temperatures, otherwise they would both slap three cores on a PCB and duke it out. its not quite that simple.

    its actually a feat of engineering in itself that AMD got this crappy single fan to cool such a powerful card. I almost choked on my cornflakes when I saw that tiny red fan, used YET again.

  7. Man I’d love four screens and two of these. Best start saving.

    Oh yeah and a new psu

    And a new CPU

    Damn…..

  8. Crazy frame rates, do we really need kind of power? Best game in months was dead space 2 and it could run well with a 6850.

    Portal 2 should be the same….

  9. Hey quick question. Whats this sticker over the bios switch, do you void warranty by running the card at full speed? Is it dangerous? I really really don’t get this…

  10. hell when you limit an overclocked 12 core intel processor at 2560 then you know you have something special !

  11. One thing is certain, you wont be running this setup on a 650W psu. I think a 1200w is a minimum for this setup. might get away with 1000w, but it would be rather highly loaded with the rest of the components in the mix.

  12. That performance is just stupid. as in stupid good, not stupid sucky.
